Since the first original printing of this card was only given to the winners of that specific tournament (and theres only about 75 or so floating around), its easy to see why the Magikarp Tamamushi promo card is worth anywhere from $15,000 to $20,000 today
So far the only set I have come across where there are long repeated sequences on a commons sheet and there is more than one possible reconstruction is Gym Challenge
And from a collecting standpoint, of course, the main chases remain the set's various Illustration Rares (and SIRs, and higher)
It is also worth noting that there is a fourth variant of Pokmon V, V-UNION, which are formed by placing down four cards together
However, if there's one Pokmon type that can ramp up energy it's water
Cards like Parapet Thrasher and Balor tend to take over games
